Deploying a Secure Multi-Tier Web Application on AWS

Design and deploy a multi-tier web application using EC2 instances within a custom VPC with public and private subnets, internet gateways, and NAT gateways. Configure IAM roles and policies to enforce least-privilege access, and use Route 53 for DNS routing and CloudFront for content delivery. Store static assets in S3 and application data in Amazon RDS with Multi-AZ deployment for high availability.

Building a Scalable Data Storage and Access Solution

Create a secure data storage architecture using Amazon S3 with bucket policies, access control lists, and lifecycle rules to transition data to S3 Glacier for cost optimization. Set up a DynamoDB table for fast key-value lookups and configure VPC endpoints to enable private access to S3 from within the VPC without traversing the public internet.

Designing an AWS Identity and Network Security Architecture

Implement a comprehensive security architecture using AWS IAM with users, groups, and roles organized under AWS Organizations for multi-account management. Configure KMS for encryption key management, set up Amazon Cognito for application user authentication, and design a VPC with bastion hosts, private subnets, and security groups to restrict and audit network access.
